About Rotating Joints
Rotating joints transfer hot and cold materials from your supply line to a continuously revolving drum, roller, or other rotating equipment.
Pipe size is an industry designation, not the actual size. View information about how to measure pipe size threads.

Aluminum One-Way-Flow Rotating Joints
- For Use With: Air, Hydraulic Oil
- Temperature Range: See table
- Maximum Pressure:
Air: 150 psi @ 72° F
Oil: See table - Maximum Vacuum: 28 in. of Hg @ 72° F
These joints have a rotating shaft with threads on one end that connect to a continuously revolving drum, roller, or other rotating equipment. Use them to transfer hot and cold materials from your supply line. Joints are for one-way flow and are meant to be used in pairs—one joint serves as the supply line while the other serves as the return line. Joints are made of lightweight aluminum. They are a compact size for use in small air and hydraulic applications.
If your drum rotates counterclockwise as you face the connecting end, you should select a rotating joint with right-handed threads.

Grease Fitting Adapters
When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.
UNF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.

Pressure Test Fittings
Check pressure without permanently installing a gauge. Fittings have an NPT male connection for installation in your pipe or tank. Wrench-tighten the fitting onto your equipment, then insert the gauge adapter (sold separately) into the fitting. Connect gauge adapters to gauges with 1/4 pipe size NPT male threads.
Fast-Acting Panel-Mount Threaded On/Off Valves
Start or stop flow with the flip of a toggle switch or the push of a button. These valves are often used in testing and sampling applications where you need to dispense a small amount of liquid. They fit through a cutout, so the body of the valve stays safe inside your instrumentation panel.
Manual-return valves stay open until you flip the toggle off. Since they don't need to be held open, they’re often used to dispense larger samples than spring-return valves. It’s also easy to check if these valves are open or not based on the toggle’s position. Spring-return valves automatically close when you release the toggle or push button. They’re ideal for intermittent use and precise flow control to prevent spills.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Fast-Acting Threaded On/Off Valves
Push a button or flip a toggle switch to start or stop flow. Often used in testing and sampling, these valves are useful when you need to dispense a small amount of liquid.
Nickel-plated brass valves resist corrosion better than plain brass valves.
Push-button valves automatically open or close when you take your finger off the button. They’re ideal for intermittent use and applications where you want to monitor flow closely to avoid spills. The button is colored to make it easy to tell different valves apart. Normally closed valves open when you push their button.
Toggle valves stay open until you flip them closed. Since they don't need to be held open, they’re often used to dispense larger samples than push-button valves. You can see if these valves are open or not based on the toggle's position.
